Properties | Ether is a diphenyl ether type of contact-killing herbicide, chemical name: 2, 4-dichlorophenyl-4 ′-nitrophenyl ether. The original drug is a light yellow needle-like crystalline solid with a melting point of 70~71 ℃ and a vapor pressure of 1066.6 × 10-6Pa at 40 ℃. |
apply | 2,4-dichloro-4'-nitrodiphenyl ether (weed ether) as a contact-killing herbicide, which can only produce virulence when light is seen, and the drug effect is not high when the temperature is below 20 ℃; When above 25 ℃ and exposed to sunlight, the drug effect is significantly increased. Eworite is a broad-spectrum herbicides, which can control barnyard grass, triangular grass, and jointed grass in rice fields. It can also be used for weeding in dry land such as cotton, peanuts, sugarcane, rape, and mulberry fields. |
Use | It is a contact herbicide used before or early after buds, used in rice or vegetable fields to control a variety of broad-leaved and narrow-leaved weeds Used as a pharmaceutical intermediate Ether is a contact herbicide used before or early after buds, which can kill most annual weeds, for example, barnyard grass, cow hair grass, duck tongue grass, three-sided grass, etc. in paddy fields can also kill crabgrass, bristlegrass, and dry barnyard grass in dry fields. For carrots, celery, cabbage and other Umbelliferae and cruciferae vegetable plots can control weeds, but also suitable for tea mulberry orchards and nurseries. It has some inhibitory effect on some perennial weeds, but it cannot be eradicated.
